Bug Minor Open Unresolved Qian Yingjin Vikentsi Lapa Fri, 7 Aug 2020 20:30:55 +0000 Sat, 8 Aug 2020 03:00:11 +0000 Lustre 2.14.0 0 4 <p>Honestly, the syntax for these rules is not very easy to parse and write, and would have been better done differently IMHO. For example, separating the configuration of the PCC device from the setting of rules, avoiding the use of complex separators for values (e.g. why do we need '<tt>'</tt> around every value), etc.  Hopefully this can be improved as part of the landing for 2.15.</p> <p>According to the "<tt>lfs-pcc.1</tt>" man page on master, there is no need for "<tt>–param</tt>", just specify the list of parameters , but maybe that is changed by the patches?  The man page says:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> # lfs pcc add /mnt/lustre /mnt/pcc "projid=\{500,1000}&amp;fname=\{*.h5},uid=1001 rwid=1" Add HSM root and Archive ID (referenced by rwid name-value pair) mapping for RW-PCC. Where "&amp;" represents the logical conjunction operator while "," represents the logical disjunction operator. The example rule means that new files are only auto cached if the project ID is either 500 or 1000 and the suffix of the file name is ah5a or the user ID is 1001. </pre> </div></div> <p> </p> <p>It worked on my testing:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> [root@qian tests]# ../utils/lctl pcc add /mnt/lustre /mnt/pcc -p <span class="code-quote">"size&gt;{100M}&amp;size&lt;{500G} roid=7 ropcc=1"</span> [root@qian tests]# ../utils/lctl pcc list /mnt/lustre pcc: - pccpath: /mnt/pcc hsmtool: posix rwid: 0 roid: 7 flags: 2e autocache: size&gt;{100M}&amp;size&lt;{500G} [root@qian tests]# ../utils/lctl pcc clear /mnt/lustre [root@qian tests]# ../utils/lctl pcc add /mnt/lustre /mnt/pcc -p <span class="code-quote">"size&gt;{100K}&amp;size&lt;{500G} roid=7 ropcc=1"</span> [root@qian tests]# ../utils/lctl pcc list /mnt/lustre pcc: - pccpath: /mnt/pcc hsmtool: posix rwid: 0 roid: 7 flags: 2e autocache: size&gt;{100K}&amp;size&lt;{500G} [root@qian tests]# ../utils/lctl pcc list /mnt/lustre [root@qian tests]# ../utils/lctl pcc clear /mnt/lustre [root@qian tests]# ../utils/lctl pcc add /mnt/lustre /mnt/pcc -p <span class="code-quote">"size&lt;{100K}&amp;size&gt;{500K} roid=7 ropcc=1"</span> </pre> </div></div> <p>I think you did not use the latest patch for testing, please download the latest Jenkins build to test it again.</p> <p>Hi Andreas,</p> <p>I will update the man page accordingly.<br/> Thanks for pointing it out.</p> <p>Qian</p> Development Rank 1|i017g7: Rank (Obsolete) 9223372036854775807 Severity
